Abstract: ABSTRACT OF THE DISCLOSURE A system for directing a web of flexible material to a predetermined location and more particularly to a system for directing the free end or tail of the web into threading engage-ment with rolls forming a nip or the like. In the system a gas such as air is directed through a restricted opening under pres-sure whereupon it attaches itself to a flow attachment surface due to the "Coanda effect", is directed to the predetermined location and entrains ambient air.  The tail of the web is placed into the path of the moving gas and entrained thereby.  The gas is moving at a velocity greater than the velocity of the moving web and thus the web tail is straightened out and directed to the predetermined location.

Abstract: ABSTRACT OF THE DISCLOSURE A multipole circuit breaker including a latch release actuator having a trip coil and a hold-in coil coaxially surrounding a plunger and mounted within a hollow cylindrical actuator support frame.  The actuator is mounted in association with a latch mechanism and includes a spring biasing the plunger toward release of the latch mechanism. The hold-in coil is responsive to voltage conditions on an external control line and serves to oppose the action of the bias spring and maintain the plunger in a position to prevent release of the latch mechanism when the voltage on the control line is above a predetermined level.  The trip coil is connected to an electronic sensing circuit which activates the trip coil upon overcurrent conditions through the circuit breaker contacts to cause the trip coil to aid the action of the bias spring and overcome the action of the hold-in coil to move the plunger into engagement with the latch mechanism, effecting release of the latch mechanism and separation of the circuit breaker contacts.

Abstract: Abstract A sealed container provided with a valve opening and a resilient valve member self-biased into closing position.  The valve is manually openable by a lever which is held in the open position by a rigid fuse-like element which melts after being subjected to sterilizing temperatures long enough to sterilize the container and its contents.  The valve then closes, sealing the container.  The valve and ~ a gasket between the container lid and base will permit leakage out of the box to permit the withdrawal of steam from the container when a vacuum is applied to the container exterior but will prevent reverse flow so that vaccum is maintained within the container once one is created. The vaccum may be released by opening the valve, which simultaneously cocks it for the next sterilizing operation. An alternate approach includes a disposable, resilient valve member which plugs into a hole in the wall of the container and covers a valve orifice into the container.  A washer-like fuse element fits into the valve member to bias it into an open position. When the fuse melts after sterilization, the valve member will snap into closed position.  Another variation of a plug valve employs a heat responsive band having one end attached to the side of the plug which is on the outer side of the plug when the plug is positioned in the container wall.  The other end of the band extends around the edge of the plug holding the edge away from a valve opening in the wall of the container.  This inner end of the band is connected through wire to a fusible pin centrally positioned on the inner side of the plug.  At the desired time, the fuse melts releasing the wire and the band shrinks or retracts, releasing the edge of the valve member allowing it to seal against the container wall.

Abstract: ABSTRACT OF THE DISCLOSURE          A self-locking hinge for interconnecting two structural elements such as sections of tent poles includes a pair of bifurcated lugs in opposed end-to-end relationship and a yoke extending between the arms of the lugs.  A pin extends through the arms of each lug and a slot or slots in the yoke for pivotally connecting the lugs to the yoke.  The pins are biased towards each other by a spring in the slot or by springs in the slots, so that projections on the arms of one lug are biased into grooves in the arms  on the other lug to lock the hinge in an open position.  In order to close the hinge, the lugs are pulled slightly apart against the action of the spring(s) to remove the protections from the grooves, permitting rotation of the lugs relative to the yoke and to each other.

Abstract: ABSTRACT OF THE DISCLOSURE        An apparatus and method for reading punched cards data volumes parallel to one edge of the card with each data column containing a coded pattern of punches wherein the card is moved past an aligned array of sensors that are mounted to be in alignment with each data column of the passing card. The invention provides for synchronously supplying a parallel digital signal accurately represents the characters encoded in each data column even though the aligned sensor array is not maintained in precise alignment with the passing data columns and/or the card is not moved past the array at a uniform rate. The synchronous reading is accomplished by sequentiallyperforming two detection sequences to detect two conditions that occur as the card and encoded data columns move by the sensors. The first detection sequence constitutes a determination that at least one unpunched card region has passed by each sensor since the start of the first detection sequence. In effect, the first detection sequence detects the passage of an unpunched region separating adjacent columns even though the moving data column band sensor array are misaligned with one another to the extent that various sensors are exposed to a punched data location at each moment of time. The second detection sequence is automatically initiated following the first detection sequence and constitutes a determination that one data has completely passed by a sensor to effectively determine that an encoded data column is just then moving beyond the sensor array. The sensor signals immediately prior to the detection of this condition constitutes, and are supplied as, a digital signal representing the chacter encoded in the passing data column. Since the first and second detection sequences are sequentially performed in accordance with the pattern of punches in the encoded data columns, synchronous card reading is effected to read each character encoded on the card.

Abstract: METHOD OF MAKING GAS DISPLAY PANEL                    WITHOUT DISCRETE PANEL SPACERS          ABSTRACT OF THE DISCLOSURE    A method is disclosed for the fabrication of a gaseous discharge display and/or memory device which provides a predetermined uniform gap between the inner walls of the gaseous discharge device without the use of spacer elements.  Sealing about the panel periphery is provided by a devitrifiable seal glass, the viscosity of which is closely controlled as a function of time and temperature.  The glass sealant, preferably in rod form, is extruded by mixing glass frit with a solvent-binder system to form a viscous slurry, extruding this slurry into rod form and thereafter sintering the rods in an oven under conditions whereby the sealant softens but does not reflow.  The devitrifiable glass during the subsequent sealing process reflows and then crystallizes, and the viscous flow varies inversely as the crystallization.  By careful control of the time, temperature, pressure and configuration of the devitrifiable sealing glass, the amount of flow of the sealing glass is controlled, and a predetermined and uniform chamber gap is provided.      The subject invention represents an improvement in the assembly of gaseous discharge devices by eliminating the requirement for spacer elements.

Abstract: VALVE ARRANGEMENT FOR HIGH VOLTAGE FUSE            ABSTRACT: A valve arrangement for high voltage fuses permits the atmosphere to be vented into the interior of the fuse when the atmospheric pressure is greater than the interior pressure of the fuse, but restricts venting back out of the fuse when the interior pressure of the fuse is greater than atmospheric pressure thereby tending to maintain a greater than atmospheric pressure on the inside of the fuse to assist in preventing moisture from entering the fuse.  The valve arrangement also enhances fuse operation.  During the interruption of relatively low current, it functions as a check valve and tends to assist in increasing the internal presure within the fuse thereby tending to accelerate contact separation.          However, at higher current levels the valve arrangement ruptures, releasing the arc gases so that there is not an adverse effect on fuse operation.

Abstract: ABSTRACT:            The complete plane of examination is irradiated in its entirely in third-generation computer tomography apparatus. The radiation behind the object is measured by means of a large number of detection elements  The reconstruction of the absorption distribution in the plane of examination is inaccurate in a region around the centre of rotation, if the sensitivity of the detection elements differs relative to each other. The invention provides im-proved reconstruction accuracy also in this region, in that the detection device comprises a number of detection elements which is larger than necessary for the measurement of the fan-shaped radiation beam per se in a direction parallel to the axis of rotation, the detection device being displaced during the measurement in the direction of the axis of rotation. It is thus achieved that the radiation behind the object is measured each time by other detection elements, so that the differences in sensitivity can be averaged.
